It has been found that treatment of 3-bromotropolon-5-yl-thiourea derivatives with a base resulted in facile formation of 7-hydroxycyclohepta[d] thiazol-6-one derivatives, with liberation of hydrogen bromide. Out of such products, 2-benzamido derivative was submitted to oxidative degradation and its structure was confirmed. Reaction of 3-bromo-5-aminotropolone and carbon disulfide, in the presence
已经发现用碱处理 3-bromotropolon-5-yl-thiourea 衍生物导致 7-羟基环庚烷 [d] thiazol-6-one 衍生物的容易形成,并释放出溴化氢。在这些产物中,2-苯甲酰氨基衍生物被氧化降解并确认其结构。发现 3-bromo-5-aminotropolone 和二硫化碳在叔胺存在下反应形成 2-巯基衍生物。该产品与上述产品的相关性证明了该结构。
